Disk Space Inode (DPS2)

Description

This probe measures the available and used space on a specific file system by inodes usage(disk partition).

Release notes

Resource configuration interface

Resource parameters

• Warning Level (in percentage): Inode usage percentage threshold from which warning are to be generated in the monitoring system (default value: 70%)
• Critical Level (in percentage): Inode usage percentage threshold from which critical alarm are to be generated in the monitoring system (default value: 90%)

Performance graphs

This probe generates 5 graphs, one for each partition (root, main, tmp, standby, data) with the following performance metrics:

• Partition usage: the amount of inodes currently in use.

Alarms

This probe can report following alarm states:

• WARNING: the warning threshold for inodes usage is exceeded.
• CRITICAL: the critical threshold for either inodes usage is exceeded.

Possible causes

• There are too many files on the filesystem.

Possible consequences

A system that runs out of inodes on a filesystem can have following consequences:

• Complete system crash, (manual) reboot required.
• Data loss because we are not able to create new files on the filesystem.
